1 PANEL.

SPECIFICATION forming part of Letters Patent No. 294,838, dated March11, 1884.

Application tiled July 2, 1883. (No model.)

To @ZZ whom it mag/f concern.-

Be it. known that I, ROBERT A. ADAMS, a citizen of the United States,residingin the city of Grand Rapids, in the county of Kent and State ofMichigan,.have invented a new and useful Improvement in Panels, of whichthe following is a specification.

It has already become difficult to procure clear stuff77 boards ofrequisite width for panels to be usedin building and manufacture, andVresort has "to be made to the jointing of several pieces to make clearboard panels of required widths. Panels of one or more boards are alsoextremelyliable to checking and splitting from the effect of changingweather, and no means have been found to prevent board Lumber clearenough to make first-class panels is, from its scarcity, very costly.Numerous substitutes for lumber in the manufacture of panels have beenproposed and their use attempted; but none has yet been found to combinethe qualities of lightness, strength, stability, the capacity to receiveand hold paint, oil, or finish without injury, with cheapness.

The object of 'my invention 4is to provide panels vand a material forpanels that possess at once the qualities of cheapness, lightness,strength, stability, and the capacity to receive and hold paint or otheriinish without softening or injuring the panel, and all without dangerof checking, splitting, or warping.

The following is a description of my invention and its manufacture: Itake two or' more sheets of woodpboard? by wood board meaning wood pulp'mixed withany suitable size. and pressed orl rolled into sheetsanddred). These sheets of wood board are of thesizeandJ shape Iwishtogive my panel. Betweenthe sheets of woodboard, or between thetwoinpanel to be made. All the several sheets of wood board and the clothare then securely cemented together with any suitable elastic waterproofglue or cement, the glue or cement being applied to the entire surfacesin Contact, and the layers are then subjected to pressure sufficient tomake all the surfaces cohere; Vhen dry the panel is complete and can beworked and used like and as a board panel.

By the employment of wood board or wood pulp in sheets I secure apanel-surface that will hold and retain oil, paint, varnish, or otherfing ish without in any manner becoming softened or injured by suchapplication, and which can be decorated and polished like board. Veneerture, or climate, never cracking, splitting, or

warping. v

Having described and explained myinvention and its purposes, what Iclaim as new, and wish to secure by Letters Patent, is-

rlhe combination, in a panel, of sheets of wood board or wood pulp withthe sheet of cloth inserted, asdescribed, and all cemented with anysuitable elastic glue or cement, substantially as described.

ROBERT A. ADAMS.
